Winter Sprinkler Switch-off, Save Water and Let the Rain Do the Work

The Winter Sprinkler Switch off is here.

From 1st June, households and businesses across Perth, Mandurah, parts of the South West and Great Southern must switch off their sprinklers until 31st August. This applies to both scheme water and bore users.

This annual initiative is a simple and effective way to make a big difference. By letting the winter rains take care of our gardens, Western Australians can help save nearly 5 billion litres of water. That is enough to fill Optus Stadium five times.

Why the Winter Sprinkler Switch off Matters

Climate change is putting more pressure on our water supplies. Every drop counts, especially in a state like WA where hot, dry summers are the norm. Winter is the perfect time to give your sprinklers a break and let nature do the watering.

Here is why switching off matters:

• Saves precious water for when it is needed most, in summer
•  Supports long-term water security across Western Australia
• Reduces pressure on water infrastructure and bore systems
•  Helps maintain healthy groundwater levels
• Encourages waterwise habits that benefit everyone

Who Needs to Switch Off?

The Winter Sprinkler Switch off is mandatory for:

• All households and businesses using scheme water or garden bores
• Residents in Perth, Mandurah, the South West (including Busselton Water and AqWest customers) and the Great Southern

If you are unsure whether you are included, check your address using the tool on the Water Corporation website.

How You Can Get Involved

With rain already forecast in the coming days, it makes sense to switch off early and get ahead. A few simple steps now can mean big water savings down the track.

Here is how to get started:

• Turn off your irrigation controller or set it to ‘rain delay’
• Check your system to make sure it is not leaking or running by mistake
• Use the winter break to service your system and replace faulty parts
• Keep an eye on rainfall and only hand-water if absolutely necessary

A Local Effort That Adds Up

Western Australians understand the value of water. Our state’s climate means we need to be smart with how we use it. The Winter Sprinkler Switch off is a practical way to make a real impact.

Every sprinkler turned off helps protect our water future. This benefits you, your neighbours and future generations.

Let Nature Do the Work

This winter, let nature take the lead. Switch off your sprinklers and enjoy the benefits of a greener garden and a more sustainable future.

Thank you for choosing to be waterwise. Together, we can shape WA’s water story for the better.
